No don't change hugo , he helps your cards. Pan isn't a life sucking cards but he has + life and you must buy him. Your deck is also 24 stars so change nerfereti to a 4 star (oshitsune,glorg,azgroth) Kenny is weak but deadly so you can buy him and test him. Imo Mojo and Hel aren't good but since you want life sucking cards keep hel and do mojo to pan.
